The American Psychological Association, the American Psychiatric Association, and the National Association of Social Workers in 2006 stated:
Currently, there is no scientific consensus about the specific factors that cause an individual to become heterosexual, homosexual, or bisexual – including possible biological, psychological, or social effects of the parents' sexual orientation. However, the available evidence indicates that the vast majority of lesbian and gay adults were raised by heterosexual parents and the vast majority of children raised by lesbian and gay parents eventually grow up to be heterosexual.
The American Academy of Pediatrics in 2004 stated:
The mechanisms for the development of a particular sexual orientation remain unclear, but the current literature and most scholars in the field state that one's sexual orientation is not a choice; that is, individuals do not choose to be homosexual or heterosexual. A variety of theories about the influences on sexual orientation have been proposed. Sexual orientation probably is not determined by any one factor but by a combination of genetic, hormonal, and environmental influences. In recent decades, biologically based theories have been favored by experts. Although there continues to be controversy and uncertainty as to the genesis of the variety of human sexual orientations, there is no scientific evidence that abnormal parenting, sexual abuse, or other adverse life events influence sexual orientation. Current knowledge suggests that sexual orientation is usually established during early childhood.
The Royal College of Psychiatrists in 2007 stated:
Despite almost a century of psychoanalytic and psychological speculation, there is no substantive evidence to support the suggestion that the nature of parenting or early childhood experiences play any role in the formation of a person's fundamental heterosexual or homosexual orientation. It would appear that sexual orientation is biological in nature, determined by a complex interplay of genetic factors and the early uterine environment. Sexual orientation is therefore not a choice.
The American Psychiatric Association stated:
Homosexuality was once thought to be the result of troubled family dynamics or faulty psychological development. Those assumptions are now understood to have been based on misinformation and prejudice. Currently there is a renewed interest in searching for biological etiologies for homosexuality.
Ja sam cuo da su uglavnom lezbejke vegetarijanke, ali ne poznajuci bas najbolje "tehnologiju", nisam siguran da ta "tehnologija" podrazumeva "kobasice sto im ulaze odpozadi".BOKI SMOKI":277fs9dv je napisao(la):^^
cesto su u gay osobe vegeterijanci. To ne zaboravite. Verovatno im je dosta kobasica sto im ulaze odpozadi, pa su presli na biljnu ishranu. Ovo zadnje shvatite kao crni humor.
